I recently kegged half of my fat tire clone and bottled the other half. The kegged beer was great. After inspection of the bottled beer I noticed that there is white crud floating on top of all of them. Has anyone seen this before? I fear this is some sort of infection. It has been about two weeks since bottling. Thanks

Sounds like an infection. Depending on what it is, it may or may not affect the beer flavor. If every bottle has this stuff, and you are certain that the keg does not, then the source of the infection was probably some of the equipment used when bottling (tubing, racking cane, etc.) and not a problem with a dirty bottle or two. I had a thin film develop on top of a porter that I bottled. Try inverting the bottles, then turn them back upright. In my case, the film basically sank to the bottom of the bottle, never to be seen again. The porter turned out quite good.

I see this when I prime with DME - sort of a waxy/oily film that floats to the top of the bottle. I saw it once on a batch of apa I brewed with 6-row too. It should go away after a while if that's what it is. It has been explained to me as protein, but I dunno. If it isn't ruined right now, drink 'em fast to be on the safe side. My .02.

Thanks to all have responded. I have taken your advice. I swirled it around and put it in the fridge overnight. Most of it settled to the bottom. There is only a slight ring around the neck. It tasted fine, but seemed way undercarbonated. It has a smoother flavor thab the beer I kegged. It has been 8 days since bottling and I used DME. Skoal!
